Narrated Salim's father: That he heard Allah's Apostle, when raising his head from bowing of the first Rak'a of the morning prayer, saying, "O Allah! Curse so-and-so and so-and-so" after he had said, "Allah hears him who sends his praises to Him. Our Lord, all the Praises are for you!" So Allah revealed:-- "Not for you (O Muhammad! )......(till the end of Verse) they are indeed wrong-doers." (3.128) Salim bin 'Abdullah said' "Allah's Apostle used to invoke evil upon Safwan bin Umaiya, Suhail bin 'Amr and Al-Harith bin Hisham. So the Verse was revealed:-- "Not for you (O Muhammad!)......(till the end of Verse) For they are indeed wrong-doers." (3.128)
